Eclipse与Struts2 问题，报异常 这是什么问题

Question

JSP代码如下，这个form表单与另一个表单都是请求一个Action的不同方法：

游戏退弹广告URL
正在使用的游戏退弹广告URL(以http://开始,只填写一个即可)
更新游戏退弹广告URL(以http://开始,只填写一个即可)

Struts.xml配置如下：

/WEB-INF/admin/gameExitAdv.jsp


/WEB-INF/admin/gameExitAdv.jsp

报的异常问题是

请各位帮我看看这是什么问题？怎么解决啊

Answer 1

检查你jar包有没有冲突。
到Web Application目录下检查你的action类有没有正确编译，我估计是你的某些类写的有问题，不能正确编译，导致其它类也没法编译了。
实在不行，就重新建个项目，把代码贴过来。
最后就是仔细检查下你的配置了，这还不行就是你RP问题了。
